[jira] [Commented] (HIVE-2290) Improve error messages for DESCRIBE command

["Carl Steinbach (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-2290?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13067327#comment-13067327 ] 

Carl Steinbach commented on HIVE-2290:
--------------------------------------

Hive's DESCRIBE command uses non-standard syntax (see HIVE-1977) which results in a lot of errors for users. Unfortunately, the current error message does not provide any help:

{noformat}
hive> CREATE DATABASE d1;
OK
hive> CREATE TABLE d1.t(x INT);
OK
hive> DESCRIBE d1.t;
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask
hive> 
{noformat}

The error message should instead say something like "Table 'd1' does not exist".
